Strongly disagree about Spotify. Quality aside, many albums simply aren't there! I have my own routine of discovering new pearls (YouTube used to help me with that years ago, nowadays it just suggests what I already viewed or some random stuff) and I set aside some time for that. After that, I choose the albums I really like, in the best quality.
The problem that Spotify actually tries to solve is that no matter how much we love that particular piece or album, we will get bored with it at some point, even if you dose your pleasure. So in theory Spotify could ease the process of finding interesting music. But in practice, I wound nothing can bet the tedious process of manual research and selection.
